## Coherence and maintainability
Profile hashes and local references passed validation when this report was generated. That checks traceability, not source truth or external URL freshness.
Profiles with unknown last substantive review date: 15. Assessment dates record this metadata review, not a new substantive validation. No age-based freshness claim is available for those profiles.

### LEARN-0012 — Does enhanced route replacement need explicit continuation and feedback policy that respects changed focus ownership?
2026-09-27 · stream F · prospective · corroboration
Before: Native controls alone do not establish enhanced focus/feedback semantics; delayed responses should respect focus moved to another surviving task. Modal return is not automatically route continuation.
Conclusion: Corroborated in 22 cases: raw same-ID link focus survives but this fragment contract leaves stale title and silent failure; authored heading/status policy works and preserves newer search focus. No AT speech or universal heading policy established.
Evidence: [NavigationFocusExperiment](../../research/reviews/NavigationFocusExperiment.md), [focus-result](../../research/experiments/navigation-history/focus-result.json), [2026-09-27-navigation-focus-effort](../../research/evolution/cycles/2026-09-27-navigation-focus-effort.json).
Remaining uncertainty: Author-model DOM evidence, no human/AT validation or independent recurrence. Delayed history focus, competing requests, delayed scripts and interrupted enhancement remain open.
Supersedes: none recorded.
